I don't remember the exact date or year when I first got this Camelbak but it's outlasted a number of girlfriends and life changes - I'm sure I had her in '98 - so sixteen years plus or more. Tonight she died. Upon opening her up tonight the membrane around the filling port tore. But this morning she ran up Brown Mountain with me for one last time which is just how I want to go, too. Thank you Camelbak for keeping me hydrated all these years - oh the adventures we've had!
